Abstract: To judge the potential utilization of Manila clam Ruditapes philippinarum for bio- restoration, Manila clam was exposed to multiple-contamination of heavy metals, nutrients and petroleum, during which its inhabits were simulated by sand, and metabolism characteristics and activity of superoxide dismutase of Manila clam were measured. The results showed that there were synergistic effects of ammonia and mercury on oxygen consumption of Manila clam; ammonia excretion rate of the clam was promoted by ammonia; there was no significant effect of heavy metals, nutrients and petroleum hydrocarbon on superoxide dismutase activities. Because of tolerances and bio- accumulations of Manila clam to heavy metals, nutrients and petroleum hydrocarbon, Manila clam might be used for bio- remediation of multiple- contamination of heavy metals, nutrients and petroleum hydrocarbon.
